Description
Technical field
The utility model relates to a kind of monitoring system, mainly is the wireless monitor system of anti-electromagnetic interference, particularly mine truck tire pressure and temperature wireless monitoring system.
Background technology
Tire pressure is the important indicator that influences running car performance and safety performance, and tire pressure is too high, can accelerate Tyte Wear, causes the explosion of crown position easily, simultaneously because of reducing with frictional ground force, also can influence deceleration and stopping performance; Tire pressure is crossed low or gas leakage, is multiplied with ground-surface friction force, also can quicken Tyte Wear, increases oil consumption simultaneously; Because tire sidewall is the weak part of tire, air pressure is crossed when hanging down, and can constantly be squeezed and stretch, and easily causes fatigue failure, blows out.So it is the important means that guarantees tire safety that tire pressure is monitored in real time.
At present, system for monitoring pressure in tyre (TPMS, Tire Pressure Monitor System) mainly is divided into two types: a kind of indirect type (Wheel-Speed Based TPMS of being, be called for short WSB), this system is that the wheel speed sensors by automobile ABS system comes the rotating speed difference between the comparative tire, to reach the purpose of monitoring tire pressure.The type system cost is relatively low, the automobile of having equipped ABS (1 wheel speed sensors of each tire equipment) only needs software is upgraded, major defect is to judge when the situation of deficencys and high-ball simultaneously two above tires, the particular location of fault tire can't be judged, tire pressure can not be reflected in real time; Another kind is direct-type (Pressure-Sensor Based TPMS, be called for short PSB), this system is by highly sensitive sensor is installed on each tire, data such as the pressure of real time monitoring tire, temperature under driving or static state, and be transmitted into receptor by wireless mode, on telltale, show various data variation.In too low or when gas leakage when tire pressure, system can auto alarm.At any time measuring the actual wink of each inside tires and press, determine easily all to be better than indirect type TPMS by the fault tire on function and performance, is the technical approach that generally adopts now.
